This invention rel tes to scribing and marking too s used primarily by bricklayers or masons for marking the angle of the end of a brick. and in'partic'ula' this invention includes a rectan ular sha ed frame having a brick receiving openinz therein and a fiange on one end. and a straight edge having an elongated slot therein and a scribe or marker thereon positioned across the face of the frame and secured in adjusted position by thumb nuts on screws.

The purpose of this invention is to provide means for accurately marking the correct angle on the ends of bricks, in arch building whereby, when the angle is determined, a plurality of bricks may be marked or cut on the same angle.

In constructing a brick arch bricklayers are required to measure the bottom length of a brick and aso the top length and these dimensions a e laid out on a brick with a sloping line connecting the ends hereof. The brick is then cut a d as bricks often shatter or break at unexpected p aces it is necessary to take the same measurements a second time in order to mark a second brick. With this thought in mind this invention contem lates a tool having a straight edge mounted on a frame whereby with a flange at the end of the frame positioned against the end of the last brick laid next to the arch the straight edge is set to the exact angle and also to the exact length of the next brick. The frame is then laced against the end or side of a brick and the bricks marked by a scribe on the straight edge.

The object of this invention is, therefore, to provide means for forming a marking tool where by the l"ngth of the brick and also the ang e of the ou er end thereof may readily be determined and also whereby the line may be marked on a brick indicates the length and angle of the extended end of the brick.

Another object of the invention is to provide a tool for marking bricks for arches that is de signed to be used in combination with bricks now in use.

A further object of the invention is to provide a tool that may readily be set to indicate the length of a brick and also the angle of the end threof which is of a simple and economical construction.

With these and other objects and advantages in view the invention embodies a substantially rectangular shape plate with a flange extended from one end, with an opening through the intermediate part thereof, the width and length of which are equal to the width and length of a common brick and also having an extended slot therein extended across the upper and lower edges, alsoacro'ss one "end, 5 and extended-tea point substantially-midway of the widthof the plate at the opposite end, a bar havingfan elongated slot the ein slidably mounted on screws extended through the slots of the plate and bar and having thumb nuts on the outer ends, and a scribe carried by the bar and positioned o engage the ed e of a brick corresponding with the opening through the plate.

Other features and advantages of the invention will app'ar from the following description taken in connection with the drawings wherein:

Figure 1 is a front elevational view of the t ol showing the scribing or marking plate positioned at an angle in relation to the frame.

Figure 2 is a plan view of the tool shown in Figure 1.

Fi ure 3 is a cross section through the tool taken on ine 33 of Figure 1.

Figure 4 is a side elevational view showing the scribing units with parts of the bar broken away.

F gu e 5 is a cross section through the scribing unit and bar, taken on line 5-5 of Figure 1.

Referrin now to the drawings wherein like reference characters denote corresponding parts the br ck measuring and marking tool of th s invention includes a frame I 0, a bar ll, screws i 2 and I3 which are provided with thumb nuts l4 and I 5 and a slider 16, which provides a marker or scribe.

The frame in is provided with a centrally posit oned openin ll, the width and length of which corres ond with similar dimensions of a brick upon which the tool is used and the border of the frame is provided with an elongated slot 58 that extends. from a point l9 at one end of the upper section of the frame, across the upper section, downwardly through an end section 20 and across a lower s ction to the end 2|. From the lower part of the end 2| the slot extends upwardlv to a point 22. The end 2| of the frame is provided with a flange 23 that is positioned to engage the end of the last brick laid next to the line of the arch when the device is used for marking bricks for an arch.

The screws l2 and I3 are provided with heads 24 and 25, respectively and with the screws slidably positioned in the slot i 8, and extended through a slot 26, in the bar II, the thumb nuts I4 and i 5 are placed on the outer ends. The nuts may be positioned with the bar free to slide longitudinally or the bar may be clamped in Q; position and the scribe or marking member actuated longtudinally onthe bar.

The scribe or marking member I 6, as illustrated in Figure 4 is provided with a thumb projection 21 to facilitate actuating the member and the opposite surface may be provided with points 28 and 29. It will be understood that the scribe or making member may be of any type or design and also that a knife, trowel, or other device may be used for marking the bricks;

With the device formed in this manner the flange 23 is placed against the lastbrick placed next to the arch and the bar II is set in the correct position to indicate the length of thenext brick and also to the correct angle for scribing the brick the edge of which is then placed in the opening H, the size of which corresponds to.

the size of bricks used in the arch, and with the brick held in position the marker or scribe: is. actuated or a line placed on the brick with the edge or the bar t! used as a.- guide.

It will beunderstood that modifications may be made the design, and. arrangement or the parts without departingf-rom the. spirit oi the invention,

What is. claimedis:

1. A brick scrib-mg tooloomprising areotangular shaped irame having side and end. bars with a flange extended tram one of. said end bars and with a slot extended. through the. side. bars one of the end bars and to a point midway oi the length of the other endv bar, pinsflhavihg heads on one end and threads on the other slidably mounted in the slot of the frame, a bar having an elongated slot therein slidably mounted on the pins, and thumb nuts threaded on the pins. for securing the bar having the elongated slot therein in adjusted positions.

2. A brick scribing tool comprising a rectangular shaped frame having side and end bars with a flange extended from one of said end bars and with a, slot, extended through the side bars, one of the end bars and toapoint midway of the length of the other end bar, pins having heads on one end and threads on the other slidably mounted in, thelslotvof the frame, a bar having an elongated slot therein slidably mounted on the pins, thumb nuts threaded on the pins for securing the bar having the elongated slot therein in adjusted positions, and a marking element slidably mounted. on the bar having an elongated slot therein.
